As we know that the nearest neighbor search is a good and effective method for large-scaled image search. This paper mainly focuses on the design and implementation of parallel image retrieval system based on Hadoop architecture and hashing binary code. Firstly, the whole architecture design of the system and the whole flow of image Hash retrieval are introduced. Then, the image feature extraction based on MAPREDUCE parallel data processing framework, as well as the next feature quantization and the construction method of the Hash index table are introduced in details. Finally, through the comparison of retrieval performances on the INRIA data set, it has been proved that the proposed system has better performance than the single node system on both the retrieval speed and the capability of dealing with massive data.
